8 Operation parameters
8.1 Operation overview
The Daniel Series 1500 LTM is a volumetric flow measuring and transmitting device that
produces an output signal proportional to the rate-of-flow of the liquid being measured.
The primary output is a single or dual high resolution signal that is amplified and shaped by
an integral preamplifier mounted within an explosion-proof housing. This square wave
pulse can be fed directly to remote totalizers, digital readout devices or control
instrumentation.
WARNING
EXCEEDING PARAMETER HAZARD
Turbine meter parameters are set for safe equipment use. Do not exceed these
parameters.
Failure to comply may result in death, serious injury and/or damage to the equipment.
8.2 Turbine meter normal operation
After any reparation or installation of a new turbine meter, calibrate it to confirm the
meter factor or establish a new meter factor for the turbine meter as it is installed at the
site.
The customer has various options to calibrate their turbine meter. Either by their on site
stationary small volume bidirectional - unidirectional or master meter. This calibration
service is also available from Daniel.
During operation, the customer data center will download to the terminal automated
system (TAS) the orders to be schedule to the pipeline to various customers. TAS and
turbine meter flow computer electronics monitor, control and collect batch volumes on
each order and return all information as if it occurs to the TAS or invoncing.
8.3 Back pressure calculation for the LTM
Flow and pressure information is stamped on the nameplate located on the outside of the
meter.
• Back pressure at the outlet of the turbine meter must be sufficient for accurate
operation.
• Consider the following equation when determining back pressure for the turbine
meter.
• Open valves slowly to prevent system shock.
• Protect the Series 1500 housing and components from external impact of any kind.
Note temperature limitations when selecting turbine meter location.
